Istio: AuthorizationPolicy serviceAccounts regex injection via unescaped dots

Impact The serviceAccounts and notServiceAccounts fields in AuthorizationPolicy incorrectly interpret dots . as a regular expression matcher. Because . is a valid character in a service account name, an AuthorizationPolicy ALLOW rule targeting SA e.g. cert-manager.io also matches cert-manager-io,...

SUSE CVE-2026-34830

Rack is a modular Ruby web server interface. Prior to versions 2.2.23, 3.1.21, and 3.2.6, Rack::Sendfilemapaccelpath interpolates the value of the X-Accel-Mapping request header directly into a regular expression when rewriting file paths for X-Accel-Redirect. Because the header value is not...

CVE-2026-34830

CVE-2026-34830 affects Rack, specifically when using Rack::Sendfile#map_accel_path prior to versions 2.2.23, 3.1.21, and 3.2.6. The vulnerability arises because the X-Accel-Mapping header value is interpolated directly into a regular expression without escaping, allowing an attacker that can supp...
